What injectors are these?

[dragrush]

I have some injectors but not sure what they are. The only thing it says on them is the # 47723 Anyone know what they are or how I can find out?
I was told when I got them that they were PTE 780cc but Im not sure

but have 47723 written on them, I have dsmlink, not sure if there is a way to figure out the size on there?

Go to the Fuel tab and post your deadtime and global % numbers. That should give us an indication as to what they might be.

Or go to the AFRatioEst properties (from the Displayed Values window) and it should say in there if the properties were set up correctly.

Shop here dyno tuned it, but im getting knock and I want to do my own tune. They set up the global to 44 and dead time at 315.....a/f ratio props say 780, but i think they were going just off what I told them I think the injector size is....and I know if they are 780.. global should be at 38
Thats why im trying to figure out what size injectors I have for sure so I can set the global/dead time right

Hmm, well, that doesn't help either if those numbers are based off of a guess.

Maybe call PTE to see if they're from them? They should be able to tell you this, whether it's a yes or no.

I assume that number is engraved/scratched into the injectors but it's not the part number.
There is a Rochester/Delphi number on them but you may have to pull then to see it.

For example 17113742 = 75lb/hr low impedance

yes the number is engraved into them, Im going to try to get hold of PTE and see if they can help me out, if not Ill prob just take the injectors out and hope to find out that way....thanks
